How to Fix / Troubleshooting

Safety first: Unplug the freezer before accessing any control boards or wiring.

  • Step 1 – Inspect harness: Locate the wiring harness between the UI (front/top panel) and the main control (rear or top). Check for pinched, cut, or damaged wires.
  • Step 2 – Reseat connectors: Disconnect and reconnect the harness connectors at both boards to ensure solid contact.
  • Step 3 – Visual board inspection: Look for burn marks or corrosion on both boards.

If F6 remains, either the UI or main control board is likely defective. Determining which requires substitution or advanced diagnostics and is best handled by a technician.
